Abstract
bomba de cateter para suporte circulatório. a presente invenção refere-se a uma bomba de cateter pretendida para ser inserida no sistema circulatório de um mamifero, por exemplo, para ajudar o coração. a bomba de cateter compreende: um cateter oco (2); um cabo de acionamento (1) disposto em um lúmen (6) do cateter (2); um revestimento (3) cicundando o cateter oco (2); um eixo de acionamento (5) conectado a uma extremidade distal do cabo de acionamento (1) para ser girado pelo cabo de acionamento; um propulsor (4) disposto no eixo de acionamento; e uma gaiola (11) circundando o propulsor. o propulsor e a gaiola são móveis a partir de uma posição dobrada, em que a bomba de cateter tem uma pequena dimensão seccional transversal de cerca de 3,3 mm, para uma posição desdobrada em que a gaiola desdobrada circunda o propulsor desdobrado e o tamanho da gaiola é de aproximandamente 19,5 mm. o eixo de acionamento compreende um mancal distal (24) e um mancal proximal (25). um sistema de purgação é disposto para passar fluido em um lúmen (7) ao longo do cateter oco para o mancal proximal, para purgação e lubrificação do mancal proximal. o fluido é retornado fora do cabo de acionamento. uma parte do fluido é passada para dentro de canais (22) para passar fluido do mancal proximal para o mancal distal, para purgação e lubrificação de mancal distal.catheter pump for circulatory support. The present invention relates to a catheter pump intended to be inserted into the circulatory system of a mammal, for example, to aid the heart. the catheter pump comprises: a hollow catheter (2); a drive cable (1) disposed in a lumen (6) of the catheter (2); a sheath (3) surrounding the hollow catheter (2); a drive shaft (5) connected to a distal end of the drive cable (1) to be rotated by the drive cable; a propeller (4) arranged on the drive shaft; and a cage (11) surrounding the impeller. the impeller and cage are movable from a folded position, where the catheter pump has a small cross-sectional dimension of about 3.3 mm, to an deployed position where the deployed cage surrounds the deployed impeller and size of cage is approximately 19.5 mm. the drive shaft comprises a distal bearing (24) and a proximal bearing (25). a purge system is arranged to pass fluid in a lumen (7) along the hollow catheter to the proximal bearing, for purging and lubricating the proximal bearing. fluid is returned outside the drive cable. a portion of the fluid is passed into channels (22) to pass fluid from the proximal bearing to the distal bearing, for distal bearing purging and lubrication.
